Isitofu samafutha e-elektroniki saziwa ngokuba yi-EUI, isebenza njani? Umgaqo wayo wokusebenza nje kukuba isibonakaliso sombane esikhutshwe yi-ECM sithunyelwa kwi-valve ye-solenoid, elawula ukuvulwa kunye nokuvala i-valve yenaliti, ngaloo ndlela idlulisela inani elithile le-fuel ngaphakathi kwe-injector. Ubungakanani kunye nobude be-injection kulawulwa ngokuchanekileyo yi-algorithm ye-ECM kunye ne-MAP. Ubungakanani benaliti yepetroli imiselwe ixesha lokutofa kunye nesantya se-injector plunger, kwaye ihambelana nomnye. Umzuzu xa i-valve ye-solenoid inikwe amandla kukuqala kwenaliti yeoli, kwaye ukulahlekelwa kwamandla kukuphela kwenaliti yeoli. Nanga amanyathelo amane okusebenza e-injector.
Ukufunxa istroke
Umjelo wamafutha uqhagamshelwe kwintloko ye-injini ye-cylinder ukuhambisa i-fuel ngentloko ye-cylinder kwi-injection nganye, ngoko ke uyilo lomgca we-fuel kufuneka uqinisekise ukuba ubushushu be-fuel buhambelana phakathi kwee-injection. Emva kokuba i-fuel igeleza kwi-injector, i-fuel igcinwa kwaye ipholile kwigumbi langaphakathi, ngelixa amanzi kunye ne-steam kwi-fuel yenziwa. Ngeli xesha lokubetha, i-injector plunger iphakama kwaye i-fuel igalela kwi-injector, igcwalise i-injector cavity.
Isibetho sokutofa
Xa i-injector plunger iqala ukuhla, i-fuel engaphantsi kwe-plunger inyanzelekile ukuba iphume kwi-injector kwaye ibuyele kwisekethe yamafutha. Ukuba i-ECM ayibonisi i-valve ye-solenoid, ngoko yonke iya kubuyela kwisiphaluka samafutha. Xa i-ECM inika umqondiso kwi-valve ye-solenoid, i-valve yenaliti elawulwa yi-valve ye-solenoid ivaliwe, kwaye i-fuel ayikwazi ukubuyela kwisiphaluka se-fuel, kwaye uxinzelelo luqhubeka lukhula njengoko i-plunger iqhubeka ihla, ibe yindawo ephakamileyo. -i-fuel yoxinzelelo, ukunyanzela ivalve yomlomo ukuba ivule kwaye iqalise ukutshiza. Uxinzelelo oluphezulu lwenaliti alukho ekuqaleni kwesitofu, kodwa kufuphi nokuphela kwesitofu.
Ukubetha okushiyekileyo
I-injection iyaqhubeka de i-valve ye-solenoid ilahlekelwe amandla, ngelo xesha i-valve yenaliti ye-solenoid ivula, i-oil-high-pressure ikhululekile, ingena kwisiphaluka se-fuel, kwaye i-valve ye-injection ivaliwe.
